+Subject: af_unix: Don't set -ECONNRESET for consumed OOB skb.
+
+From: Kuniyuki Iwashima <kuniyu@google.com>
+
+[ Upstream commit 2a5a4841846b079b5fca5752fe94e59346fbda40 ]
+
+Christian Brauner reported that even after MSG_OOB data is consumed,
+calling close() on the receiver socket causes the peer's recv() to
+return -ECONNRESET:
+
+  1. send() and recv() an OOB data.
+
+    >>> from socket import *
+    >>> s1, s2 = socketpair(AF_UNIX, SOCK_STREAM)
+    >>> s1.send(b'x', MSG_OOB)
+    1
+    >>> s2.recv(1, MSG_OOB)
+    b'x'
+
+  2. close() for s2 sets ECONNRESET to s1->sk_err even though
+     s2 consumed the OOB data
+
+    >>> s2.close()
+    >>> s1.recv(10, MSG_DONTWAIT)
+    ...
+    ConnectionResetError: [Errno 104] Connection reset by peer
+
+Even after being consumed, the skb holding the OOB 1-byte data stays in
+the recv queue to mark the OOB boundary and break recv() at that point.
+
+This must be considered while close()ing a socket.
+
+Let's skip the leading consumed OOB skb while checking the -ECONNRESET
+condition in unix_release_sock().

+Subject: ALSA: usb-audio: Fix out-of-bounds read in
+ snd_usb_get_audioformat_uac3()
+
+From: Youngjun Lee <yjjuny.lee@samsung.com>
+
+[ Upstream commit fb4e2a6e8f28a3c0ad382e363aeb9cd822007b8a ]
+
+In snd_usb_get_audioformat_uac3(), the length value returned from
+snd_usb_ctl_msg() is used directly for memory allocation without
+validation. This length is controlled by the USB device.
+
+The allocated buffer is cast to a uac3_cluster_header_descriptor
+and its fields are accessed without verifying that the buffer
+is large enough. If the device returns a smaller than expected
+length, this leads to an out-of-bounds read.
+
+Add a length check to ensure the buffer is large enough for
+uac3_cluster_header_descriptor.

+
+From: Vijendar Mukunda <Vijendar.Mukunda@amd.com>
+
+[ Upstream commit dc6458ed95e40146699f9c523e34cb13ff127170 ]
+
+During the hibernate entry sequence, ACP registers will be reset to
+default values and acp ip will be completely powered off including acp
+SoundWire pads. During resume sequence, if acp SoundWire pad keeper enable
+register is not restored along with pad pulldown control register value,
+then SoundWire manager links won't be powered on correctly results in
+peripheral register access failures and completely audio function is
+broken.
+
+Add code to store the acp SoundWire pad keeper enable register and acp pad
+pulldown ctrl register values before entering into suspend state and
+restore the register values during resume sequence based on condition check
+for acp SoundWire pad keeper enable register for ACP6.3, ACP7.0 & ACP7.1
+platforms.

+Subject: atm: Release atm_dev_mutex after removing procfs in
+ atm_dev_deregister().
+
+From: Kuniyuki Iwashima <kuniyu@google.com>
+
+[ Upstream commit a433791aeaea6e84df709e0b9584b9bbe040cd1c ]
+
+syzbot reported a warning below during atm_dev_register(). [0]
+
+Before creating a new device and procfs/sysfs for it, atm_dev_register()
+looks up a duplicated device by __atm_dev_lookup().  These operations are
+done under atm_dev_mutex.
+
+However, when removing a device in atm_dev_deregister(), it releases the
+mutex just after removing the device from the list that __atm_dev_lookup()
+iterates over.
+
+So, there will be a small race window where the device does not exist on
+the device list but procfs/sysfs are still not removed, triggering the
+splat.
+
+Let's hold the mutex until procfs/sysfs are removed in
+atm_dev_deregister().

+
+[ Upstream commit ce7df19686530920f2f6b636e71ce5eb1d9303ef ]
+
+If we are propagating across the userns boundary, we need to lock the
+mounts added there.  However, in case when something has already
+been mounted there and we end up sliding a new tree under that,
+the stuff that had been there before should not get locked.
+
+IOW, lock_mnt_tree() should be called before we reparent the
+preexisting tree on top of what we are adding.

+Subject: Bluetooth: hci_core: Fix use-after-free in vhci_flush()
+
+From: Kuniyuki Iwashima <kuniyu@google.com>
+
+[ Upstream commit 1d6123102e9fbedc8d25bf4731da6d513173e49e ]
+
+syzbot reported use-after-free in vhci_flush() without repro. [0]
+
+From the splat, a thread close()d a vhci file descriptor while
+its device was being used by iotcl() on another thread.
+
+Once the last fd refcnt is released, vhci_release() calls
+hci_unregister_dev(), hci_free_dev(), and kfree() for struct
+vhci_data, which is set to hci_dev->dev->driver_data.
+
+The problem is that there is no synchronisation after unlinking
+hdev from hci_dev_list in hci_unregister_dev().  There might be
+another thread still accessing the hdev which was fetched before
+the unlink operation.
+
+We can use SRCU for such synchronisation.
+
+Let's run hci_dev_reset() under SRCU and wait for its completion
+in hci_unregister_dev().
+
+Another option would be to restore hci_dev->destruct(), which was
+removed in commit 587ae086f6e4 ("Bluetooth: Remove unused
+hci-destruct cb").  However, this would not be a good solution, as
+we should not run hci_unregister_dev() while there are in-flight
+ioctl() requests, which could lead to another data-race KCSAN splat.
+
+Note that other drivers seem to have the same problem, for exmaple,
+virtbt_remove().

+
+From the crash dump, we found that the cpu_map_flush_list inside
+redirect info is partially corrupted: its list_head->next points to
+itself, but list_head->prev points to a valid list of unflushed bq
+entries.
+
+This turned out to be a result of missed XDP flush on redirect lists. By
+digging in the actual source code, we found that
+commit 7f0a168b0441 ("bnxt_en: Add completion ring pointer in TX and RX
+ring structures") incorrectly overwrites the event mask for XDP_REDIRECT
+in bnxt_rx_xdp. We can stably reproduce this crash by returning XDP_TX
+and XDP_REDIRECT randomly for incoming packets in a naive XDP program.
+Properly propagate the XDP_REDIRECT events back fixes the crash.

+Subject: bridge: mcast: Fix use-after-free during router port configuration
+
+From: Ido Schimmel <idosch@nvidia.com>
+
+[ Upstream commit 7544f3f5b0b58c396f374d060898b5939da31709 ]
+
+The bridge maintains a global list of ports behind which a multicast
+router resides. The list is consulted during forwarding to ensure
+multicast packets are forwarded to these ports even if the ports are not
+member in the matching MDB entry.
+
+When per-VLAN multicast snooping is enabled, the per-port multicast
+context is disabled on each port and the port is removed from the global
+router port list:
+
+ # ip link add name br1 up type bridge vlan_filtering 1 mcast_snooping 1
+ # ip link add name dummy1 up master br1 type dummy
+ # ip link set dev dummy1 type bridge_slave mcast_router 2
+ $ bridge -d mdb show | grep router
+ router ports on br1: dummy1
+ # ip link set dev br1 type bridge mcast_vlan_snooping 1
+ $ bridge -d mdb show | grep router
+
+However, the port can be re-added to the global list even when per-VLAN
+multicast snooping is enabled:
+
+ # ip link set dev dummy1 type bridge_slave mcast_router 0
+ # ip link set dev dummy1 type bridge_slave mcast_router 2
+ $ bridge -d mdb show | grep router
+ router ports on br1: dummy1
+
+Since commit 4b30ae9adb04 ("net: bridge: mcast: re-implement
+br_multicast_{enable, disable}_port functions"), when per-VLAN multicast
+snooping is enabled, multicast disablement on a port will disable the
+per-{port, VLAN} multicast contexts and not the per-port one. As a
+result, a port will remain in the global router port list even after it
+is deleted. This will lead to a use-after-free [1] when the list is
+traversed (when adding a new port to the list, for example):
+
+ # ip link del dev dummy1
+ # ip link add name dummy2 up master br1 type dummy
+ # ip link set dev dummy2 type bridge_slave mcast_router 2
+
+Similarly, stale entries can also be found in the per-VLAN router port
+list. When per-VLAN multicast snooping is disabled, the per-{port, VLAN}
+contexts are disabled on each port and the port is removed from the
+per-VLAN router port list:
+
+ # ip link add name br1 up type bridge vlan_filtering 1 mcast_snooping 1 mcast_vlan_snooping 1
+ # ip link add name dummy1 up master br1 type dummy
+ # bridge vlan add vid 2 dev dummy1
+ # bridge vlan global set vid 2 dev br1 mcast_snooping 1
+ # bridge vlan set vid 2 dev dummy1 mcast_router 2
+ $ bridge vlan global show dev br1 vid 2 | grep router
+       router ports: dummy1
+ # ip link set dev br1 type bridge mcast_vlan_snooping 0
+ $ bridge vlan global show dev br1 vid 2 | grep router
+
+However, the port can be re-added to the per-VLAN list even when
+per-VLAN multicast snooping is disabled:
+
+ # bridge vlan set vid 2 dev dummy1 mcast_router 0
+ # bridge vlan set vid 2 dev dummy1 mcast_router 2
+ $ bridge vlan global show dev br1 vid 2 | grep router
+       router ports: dummy1
+
+When the VLAN is deleted from the port, the per-{port, VLAN} multicast
+context will not be disabled since multicast snooping is not enabled
+on the VLAN. As a result, the port will remain in the per-VLAN router
+port list even after it is no longer member in the VLAN. This will lead
+to a use-after-free [2] when the list is traversed (when adding a new
+port to the list, for example):
+
+ # ip link add name dummy2 up master br1 type dummy
+ # bridge vlan add vid 2 dev dummy2
+ # bridge vlan del vid 2 dev dummy1
+ # bridge vlan set vid 2 dev dummy2 mcast_router 2
+
+Fix these issues by removing the port from the relevant (global or
+per-VLAN) router port list in br_multicast_port_ctx_deinit(). The
+function is invoked during port deletion with the per-port multicast
+context and during VLAN deletion with the per-{port, VLAN} multicast
+context.
+
+Note that deleting the multicast router timer is not enough as it only
+takes care of the temporary multicast router states (1 or 3) and not the
+permanent one (2).

+Subject: cxl/ras: Fix CPER handler device confusion
+
+From: Dan Williams <dan.j.williams@intel.com>
+
+[ Upstream commit 3c70ec71abdaf4e4fa48cd8fdfbbd864d78235a8 ]
+
+By inspection, cxl_cper_handle_prot_err() is making a series of fragile
+assumptions that can lead to crashes:
+
+1/ It assumes that endpoints identified in the record are a CXL-type-3
+   device, nothing guarantees that.
+
+2/ It assumes that the device is bound to the cxl_pci driver, nothing
+   guarantees that.
+
+3/ Minor, it holds the device lock over the switch-port tracing for no
+   reason as the trace is 100% generated from data in the record.
+
+Correct those by checking that the PCIe endpoint parents a cxl_memdev
+before assuming the format of the driver data, and move the lock to where
+it is required. Consequently this also makes the implementation ready for
+CXL accelerators that are not bound to cxl_pci.

+Subject: drm/amd: Adjust output for discovery error handling
+
+From: Mario Limonciello <mario.limonciello@amd.com>
+
+[ Upstream commit 73eab78721f7b85216f1ca8c7b732f13213b5b32 ]
+
+commit 017fbb6690c2 ("drm/amdgpu/discovery: check ip_discovery fw file
+available") added support for reading an amdgpu IP discovery bin file
+for some specific products. If it's not found then it will fallback to
+hardcoded values. However if it's not found there is also a lot of noise
+about missing files and errors.
+
+Adjust the error handling to decrease most messages to DEBUG and to show
+users less about missing files.

+Subject: drm/bridge: ti-sn65dsi86: Add HPD for DisplayPort connector type
+
+From: Jayesh Choudhary <j-choudhary@ti.com>
+
+[ Upstream commit 55e8ff842051b1150461d7595d8f1d033c69d66b ]
+
+By default, HPD was disabled on SN65DSI86 bridge. When the driver was
+added (commit "a095f15c00e27"), the HPD_DISABLE bit was set in pre-enable
+call which was moved to other function calls subsequently.
+Later on, commit "c312b0df3b13" added detect utility for DP mode. But with
+HPD_DISABLE bit set, all the HPD events are disabled[0] and the debounced
+state always return 1 (always connected state).
+
+Set HPD_DISABLE bit conditionally based on display sink's connector type.
+Since the HPD_STATE is reflected correctly only after waiting for debounce
+time (~100-400ms) and adding this delay in detect() is not feasible
+owing to the performace impact (glitches and frame drop), remove runtime
+calls in detect() and add hpd_enable()/disable() bridge hooks with runtime
+calls, to detect hpd properly without any delay.
+

+[ Upstream commit d02b2103a08b6d6908f1d3d8e8783d3f342555ac ]
+
+An earlier patch fixed a build failure with clang, but I still see the
+same problem with some configurations using gcc:
+
+drivers/gpu/drm/i915/i915_pmu.c: In function 'config_mask':
+include/linux/compiler_types.h:568:38: error: call to '__compiletime_assert_462' declared with attribute error: BUILD_BUG_ON failed: bit > BITS_PER_TYPE(typeof_member(struct i915_pmu, enable)) - 1
+drivers/gpu/drm/i915/i915_pmu.c:116:3: note: in expansion of macro 'BUILD_BUG_ON'
+  116 |   BUILD_BUG_ON(bit >
+
+As I understand it, the problem is that the function is not always fully
+inlined, but the __builtin_constant_p() can still evaluate the argument
+as being constant.
+
+Marking it as __always_inline so far works for me in all configurations.

+
+[ Upstream commit fb721b2c35b1829b8ecf62e3adb41cf30260316a ]
+
+The drm_writeback_connector_cleanup have the signature:
+
+     static void drm_writeback_connector_cleanup(
+               struct drm_device *dev,
+               struct drm_writeback_connector *wb_connector)
+
+But it is stored and used as a drmres_release_t
+
+    typedef void (*drmres_release_t)(struct drm_device *dev, void *res);
+
+While the current code is valid and does not produce any warning, the
+CFI runtime check (CONFIG_CFI_CLANG) can fail because the function
+signature is not the same as drmres_release_t.
+
+In order to fix this, change the function signature to match what is
+expected by drmres_release_t.

+During driver probe we might be briefly using CT safe mode, which
+is based on a delayed work, but usually we are able to stop this
+once we have IRQ fully operational.  However, if we abort the probe
+quite early then during unwind we might try to destroy the workqueue
+while there is still a pending delayed work that attempts to restart
+itself which triggers a WARN.
+
+This was recently observed during unsuccessful VF initialization:

+From: Even Xu <even.xu@intel.com>
+
+[ Upstream commit 73f3a7415d93cf418c7625d03bce72da84344406 ]
+
+During customer board enabling, it was found: some touch devices
+prepared reset response, but either forgot sending interrupt or
+THC missed reset interrupt because of timing issue. THC QuickI2C
+driver depends on interrupt to read reset response, in this case,
+it will cause driver waiting timeout.
+
+This patch enhances the flow by adding manually reset response
+reading after waiting for reset interrupt timeout.

+Subject: HID: wacom: fix crash in wacom_aes_battery_handler()
+
+From: Thomas Zeitlhofer <thomas.zeitlhofer+lkml@ze-it.at>
+
+[ Upstream commit f3054152c12e2eed1e72704aff47b0ea58229584 ]
+
+Commit fd2a9b29dc9c ("HID: wacom: Remove AES power_supply after extended
+inactivity") introduced wacom_aes_battery_handler() which is scheduled
+as a delayed work (aes_battery_work).
+
+In wacom_remove(), aes_battery_work is not canceled. Consequently, if
+the device is removed while aes_battery_work is still pending, then hard
+crashes or "Oops: general protection fault..." are experienced when
+wacom_aes_battery_handler() is finally called. E.g., this happens with
+built-in USB devices after resume from hibernate when aes_battery_work
+was still pending at the time of hibernation.
+
+So, take care to cancel aes_battery_work in wacom_remove().

+A bigger array of vecs could've been allocated, but

+Subject: libbpf: Fix possible use-after-free for externs
+
+From: Adin Scannell <amscanne@meta.com>
+
+[ Upstream commit fa6f092cc0a02d0fcee37e9e8172eda372a03d33 ]
+
+The `name` field in `obj->externs` points into the BTF data at initial
+open time. However, some functions may invalidate this after opening and
+before loading (e.g. `bpf_map__set_value_size`), which results in
+pointers into freed memory and undefined behavior.
+
+The simplest solution is to simply `strdup` these strings, similar to
+the `essent_name`, and free them at the same time.
+
+In order to test this path, the `global_map_resize` BPF selftest is
+modified slightly to ensure the presence of an extern, which causes this
+test to fail prior to the fix. Given there isn't an obvious API or error
+to test against, I opted to add this to the existing test as an aspect
+of the resizing feature rather than duplicate the test.

+Subject: net: enetc: Correct endianness handling in _enetc_rd_reg64
+
+From: Simon Horman <horms@kernel.org>
+
+[ Upstream commit 7b515f35a911fdc31fbde6531828dcd6ae9803d3 ]
+
+enetc_hw.h provides two versions of _enetc_rd_reg64.
+One which simply calls ioread64() when available.
+And another that composes the 64-bit result from ioread32() calls.
+
+In the second case the code appears to assume that each ioread32() call
+returns a little-endian value. However both the shift and logical or
+used to compose the return value would not work correctly on big endian
+systems if this were the case. Moreover, this is inconsistent with the
+first case where the return value of ioread64() is assumed to be in host
+byte order.
+
+It appears that the correct approach is for both versions to treat the
+return value of ioread*() functions as being in host byte order. And
+this patch corrects the ioread32()-based version to do so.
+
+This is a bug but would only manifest on big endian systems
+that make use of the ioread32-based implementation of _enetc_rd_reg64.
+While all in-tree users of this driver are little endian and
+make use of the ioread64-based implementation of _enetc_rd_reg64.
+Thus, no in-tree user of this driver is affected by this bug.
+
+Flagged by Sparse.
+Compile tested only.

+Subject: riscv: fix runtime constant support for nommu kernels
+
+From: Charles Mirabile <cmirabil@redhat.com>
+
+[ Upstream commit 8d90d9872edae7e78c3a12b98e239bfaa66f3639 ]
+
+the `__runtime_fixup_32` function does not handle the case where `val` is
+zero correctly (as might occur when patching a nommu kernel and referring
+to a physical address below the 4GiB boundary whose upper 32 bits are all
+zero) because nothing in the existing logic prevents the code from taking
+the `else` branch of both nop-checks and emitting two `nop` instructions.
+
+This leaves random garbage in the register that is supposed to receive the
+upper 32 bits of the pointer instead of zero that when combined with the
+value for the lower 32 bits yields an invalid pointer and causes a kernel
+panic when that pointer is eventually accessed.
+
+The author clearly considered the fact that if the `lui` is converted into
+a `nop` that the second instruction needs to be adjusted to become an `li`
+instead of an `addi`, hence introducing the `addi_insn_mask` variable, but
+didn't follow that logic through fully to the case where the `else` branch
+executes. To fix it just adjust the logic to ensure that the second `else`
+branch is not taken if the first instruction will be patched to a `nop`.

+Once want_mount_setattr() has returned a positive, it does require
+finish_mount_kattr() to release ->mnt_userns.  Failing do_mount_setattr()

+
+[ Upstream commit f61c7b3d442bef91dd432d468d08f72eadcc3209 ]
+
+Currently before iterating through valid links we are utilizing
+open-coding when checking if vif valid_links is a non-zero value.
+
+Add new macro, for_each_link_data(), which iterates through link_id
+and checks if it is set on vif valid_links. If it is a valid link then
+access link data for that link id.
